State one way in which the sperm cell is different from cells in the developing fetus
Answer:
An egg cell is bigger than a sperm cell.
Explanation:
An egg cell is bigger than a sperm cell. Usually, the eggs are released during the woman’s menstrual cycle. When a baby girl is born, she is automatically born with millions of egg cells, while sperm cells are constantly being reproduced in males.One way in which the sperm cell is different from cells in the developing fetus is that the sperm cell is a haploid cell while the cells in developing fetus are diploid cells.
Sperm and egg cells are derived from meiotic division of parts of the male and female's reproductive organs respectively.
Meiosis, the division of sex cells, leads to daughter cells with half the genetic materials of the parent cells which are naturally diploid (2n). These daughter cells are also referred to haploid cells (n).
A fetus is formed from the combination of a haploid sperm (n) and a haploid egg (n) resulting in a diploid (2n) structure.
Thus, the cells in the developing fetus are diploid because they are formed from the combination of 2 haploid cells - the sperm and the egg.

Describe the process and end result of meiosis.
Answer: In humans, meiosis is the process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis. In females, meiosis begins during the fetal stage when a series of diploid cells enter meiosis I. At the conclusion of meiosis I, the process comes to a halt, and the cells gather in the ovaries. At puberty, meiosis resumes. One cell at the end of meiosis I enters meiosis II each month. The result of meiosis II is a single egg cell per cycle (the other meiotic cells disintegrate). Each egg cell contains 23 chromosomes and is haploid. The union of the egg cell and the sperm cell leads to the formation of a fertilized egg cell with 46 chromosomes, or 23 pairs. Fertilization restores the diploid number of chromosomes. The fertilized egg cell, a diploid, is a zygote. Further divisions of the zygote by mitosis eventually yield a complete human being.
Answer:
In meiosis-II the separation of two chromatids occur so that equal number of chromatids (in fact chromosome due to duplication of genetic material) goes to each of the daughter cell. Thus, at the end of meiosis-II, four daughter cells are formed. Each cell has half the number of chromosomes present in the diploid cell.Feb

what should I do when my family makes fun of me because i have Entomophobia (fear of any insect) everytime i go outside and see a cicada or ladybug or something like that they said oh stop crying (im crying by just being by them) its just a bug i thought a raised a strong kid (im a girl)
and it makes my anxiety worse and just makes me sad and mad that they have the nerve to say that
Answer:
It depends on who is making fun of you. If your parents are making fun of you, then they aren't very good parents. If your siblings are making fun of you, it's normal, but tell your parents when they make fun of you or tell them to stop.
Also, being afraid of wasps and spiders is common, but being afraid of a ladybug is a little strange in my opinion.

Why are physical and behavioral adaptations important for a sunflowers survival?
Answer:
The sunflower is intolerant to shade exposure and needs full sun exposure. It has adapted to this necessity by having a heliotropic head which rotates to follow the sun, hence the name sunflower. The heads of the sunflower are heliotropic, meaning movement of the head in response to the direction of the sun.

According to Gregor Mendel’s laws of genetics inheritance, when two parents have different genes for a trait, one form of the trait will be dominant and the other recessive. The dominant form normally appears in the offspring. In this illustration, one car parent has genes for gray fur and the other genes for white fur. Gray fur is dominant. The gene for gray fur is A. The gene for white fur is a. What color would the kittens have to be in order to provide evidence supporting Mendel’s laws?

hey im not very good with science at all and i need help with this please
1. Consumers and producers both need nutrients to carry our life functions. On the other hand, producers are organisms that make their own food. Consumers are organisms that need to eat other organisms to obtain energy.
2. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers. Mold plays a big part in material biodegradation, enabling decay and rot necessary in all ecosystems.
3. The form of energy entering the food chain is sunlight, which is being taken by plants to produce glucose as their food energy. When it leaves the food chain, the energy is then heat.
4. The percentage of the energy stored by the grass that is passed onto the hawk is 1%
5. B because you can get more production from the cow's milk and meat.
Answer:
1.) Producers are organisms that are usually autotrophs and make their own food in the ecosystem by the process of Photosynthesis, using sunlight, to provide energy to themselves and later to consumers in the environment. Consumers on the other hand are organisms in an ecosystem that don't make their own food and get the energy from consuming producers, primary consumers or secondary consumers. There are 3 different types of consumers, herbivores, carnivores and omnivores.
2.) The roles of decomposers in an ecosystem is very crucial, they feed on dead and decaying bodies. Therefore these decomposers are in-charge or removing dead matter from ecosystem as well as giving energy back to the ecosystem, as where it started from.
3.) Energy enters a food chain in the form of sunlight, and leaves the food chain in the form of heat.
4.) grass = 100%; rabbit = 100% x 0.10 = 10%; hawk = 10% x 0.10 = 1%
5.) Option B, since receiving meat and milk and other dairy products would be more nutritious to the farmer's family than to eat corn most of the time
Hope this helps!

Wetlands are
areas where water covers the soil. Swamps, marshes, and other wetland
areas help to control flooding because they naturally hold water. Wetland regeneration
is a recent trend in conservation.
In some areas, land previously used for farming iS
being converted into wetlands.
Research wetlands, the types of organisms that live there, and examples of wetland
restoration and regeneration. Then answer these questions:
What factors do scientists need to
consider before turning farmland into wetlands?
How could wetland restoration affect humans who live in the area? How might it
affect native wildlife? (Consider both positive and negative consequences.)
If you were planning a wetland regeneration project,
success?
how would you monitor its
Answer:
I think its great that farmland is being converted to wetlands, wetlands reduce the amount of co2 in the air and prevent floods. Some factors scientist need to consider is how wetlands can affect civillians as wetlands can lure dangerous animals such as alligators. Converting farmland to wetland would be successful due to the fact that wetlands can provide shelter to animals and can reduce co2 in the air, I recommend researching the topic further and to take my word with a grain of salt.
Explanation:
The bottom explanation might be a little worse due to the fact that I want it to be somewhat different from the top one, both explanations work fine in my opinion but the top one is better.
Another great explanation is: I believe wetlands are amazing for the enviroment as they prevent floods and give shelter to animals, wetlands can't really affect civillians negatively other then dangerous animals. I would most likely moniter its success by seeing how much water the wetland can hold, if it can hold an average amount then I would say the restoration was successful.
How does a frog embryo compare with a human embryo?
Answer:
bec its organs are have some of the organs that humans have example like a mouse or a rat
Explanation:
It is crucial to remember that these are merely broad generalisations and that different species and even different embryos can exhibit different specific processes and traits.
Human and frog embryos are similar and different in certain ways. These comparisons are provided: Size: Compared to human embryos, frog embryos are substantially smaller. Frog embryos grow to their full size in a few of weeks, but human embryos expand significantly over the course of nine months. Developmental phases: The stages of gastrulation, neurulation, and organogenesis are shared by frog and human embryos. The precise timing and information can change, though. Internal vs. external development: Human embryos develop internally in the uterus of the mother, whereas frog embryos externally develop in a watery environment.
